4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM) is a red laser dye that consists of dicyanomethylene as an electron acceptor and dimethylaniline group as an electron donor. It has a π-conjugated 4H-pyran-4-ylidiene which bridges both the acceptor/donor groups. It can be used as a dopant and also in organic solid state lasers.
